The pile-up was triggered when a Ferrari driver lost control while trying to overtake on a bend, hit the median barrier and caused the other vehicles to smash into each other.
In March 2013, Japanese authorities said they want to charge ten drivers involved in the Rs 125-million supercar pile-up.
Police sent a case against a 61-year-old man and nine others to prosecutors on suspicion of violating traffic laws. The final decision on whether to charge the drivers rests with prosecutors.
Police say ten drivers, aged between 38 and 61, were exceeding the speed limit or not paying attention to the road.
At the time of the accident, television showed footage of the badly crumpled cars, most of them red, some with airbags deployed during a smash that injured six people.
Tanaka said: "It's rare to see a chain-reaction accident like this involving expensive cars. Some of the drivers told us they didn't really know the specifications of their cars or just how powerful their acceleration was."
The drivers were on their way to a supercar event in Hiroshima.
